I do have a perfecting fine ZX-6R that just collects dust in my garage. I dunno what's wrong with me....
    Thanks for the answer, and yes, I know that sensation Ha Ha Ha, is addictive

    Yes big difference between a 2v vers a 4v head.

    If you have a old tired engine with 7-10K WOT miles on the engine do yourself a favor and replace all the transmission bearings, they are cheap and will make your transmission happy again. Would I go 5 speed yes. I have Zero issues with my Takegawa 5 speed and I even did not have to buy a speed healer or special adaptor for my speedo everything worked plug and play.

    Just monitor your temps on your head, cylinder and oil and you would be ok. I found on my Takegawa 181-4v build the average temps on the head are between 190-220F, the cylinder between 190-240F, and oil between 160-210F going between 35mph to 55mph, anything over that and you are seeing 240F on the cylinder, 220F on the head and 220F on the oil and rise as you go up in mph like say up to 80mph for long distance.

    Awesome info, how and where exactly do the temp gauge leads attach to the motor? What would you do differently, if anything? I NEED that setup. I like the NASA look, functional techno-bling is my term. Thanks again for your years of R n D.

    I have a TTO head temp gauge which reads from the base of the spark plug. I also read the oil temp off the aRacer display. Before I had the aRacer ecu, I was using the OPMID oil temp gauge which reads off the stock oil temp sensor. The TTO head temp gauge ($45-55) is for sure the most important thing to have. From all the sources I've found on air-cooled engines, you don't want to see temps go over 375F. Cisco is running the OPMID oil temp gauge and AFR gauge on a fancy mount. Plus his fancy temp gauge, not sure where he is pulling head temps from.

    I use this cheap and it works. I mount it on a smartphone bike/MC holder using double back tape and I spray hair spray over the edge of the face to make it water proof to keep water out. Only thing missing is a led light for checking the meter reading at night and I might DIY the case to have some kind of night vision reading. One of the leads go to the head and the other one goes to the cylinder and using the mounting bolts on the head and cylinder as the connection point for the meter.

    Thanks. I will order the tto temp gauge. Head temp below 375, got it!
